Squatting test: A posture to study and counteract cardiovascular abnormalities associated with autonomic dysfunction. [PDF]

, 2011
The squatting test is an active posture manoeuvre that imposes one of the most potent orthostatic stresses. In normal subjects, the changes in blood pressure and heart rate are transient because of appropriate baroreflex homeostasis and do not provoke ...

Case report: Epidural blood patches are effective in treating intracranial hypotension due to a subarachnoid-pleural fistula

Frontiers in Surgery, 2022
BackgroundIntracranial hypotension (IH) is usually associated with cerebrospinal fluid (CSF) leakage and/or CSF hypotension, and epidural blood patch (EBP) therapy has been proven to be effective for treating spontaneous IH and post-dural puncture ...

Progressively invalidating orthostatic hypotension: A common symptom for a challenging diagnosis

Journal of Research in Medical Sciences, 2016
We discuss here an uncommon condition of neurogenic hypotension in the context of immunoglobulin light chain (amyloid light-chain) amyloidosis. The most serious feature was autonomic nervous system impairment, mainly characterized by severe refractory ...

Sudomotor and cardiovascular dysfunction in patients with early untreated Parkinson's disease. [PDF]

, 2014
BACKGROUND: According to Braak staging of Parkinson's disease (PD), detection of autonomic dysfunction would help with early diagnosis of PD. OBJECTIVE: To determine whether the autonomic nervous system is involved in the early stage of PD, we evaluated ...

Reduced brainstem functional connectivity in patients with peripheral autonomic failure

NeuroImage: Clinical, 2019
Autonomic homeostasis is dependent upon several brainstem nuclei, as well as several cortical and subcortical structures. Together, these sites make up, in part, the central autonomic network.

Reliability of orthostatic beat-to-beat blood pressure tests: implications for population and clinical studies [PDF]

, 2017
Objective: To assess the test–retest reliability of orthostatic beat-to-beat blood pressure responses to active standing and related clinical definitions of orthostatic hypotension. Methods: A random sample of community-dwelling older adults from the pan-
